Now that you mention how to check...

We don't always have to re-invent the wheel. Just go ahead and see what
other distributions are doing with their perl: run
	- perl -MConfig -e "print \$Config{'useshrplib'}" and
	- perl -V:usethreads

Here are some results:
	- Debian stable: perl +shared +threads
	- Ubuntu 11.04: perl +shared +threads
	- Mac OS X (/usr/bin/perl): perl +shared +threads
So the question rather is: Why are we doing things different than the
rest of the world here?
